Some time ago, I wrote about the Release Updates for Oracle Database 12c Release 2 (Database ). On Monday August 14th, released new Release Updates (12.2.0.1.170814) which replaces the Release Updates from July.

The patch numbers are:

26610291 for the Grid Infrastructure Release Update 12.2.0.1.170814

26609816 for the Database Release Update 12.2.0.1.170814

There is no updated RU for the OJVM RU (Patch 25811364).

According to the MOS notes, some customers had database startup issues with the first RU.

Since Oracle 11.2.02. Oracle has integrated the Cluster Verification Utility (CVU) as a cluster resource. It‘s invoked every 6 hours and checks of your cluster. If you think, this is too often, you can change the interval. I‘ll show you how.

The CHECK_INTERVAL is the interval (in seconds) which is used by the clusterware to check the availability of the cvu daemon. The RUN_INTERVAL is the interval in which CVU is started by the clusterware. It is reported in seconds (21600 seconds = 360 minutes = 6 hours).

We want to change the RUN_INTERVAL. As with „ora.*“-resource we must not use the command „crsctl modify resource“ to change the settings. Trying to do so will lead to the following message

grid@ernie:~/[-MGMTDB] crsctl modify resource ora.cvu -attr"RUN_INTERVAL=86400"
CRS-4995: The command'Modify resource' is invalid in crsctl. Use srvctl for this command.

One of the first steps after setting up an Oracle cluster is patching the Grid Infrastructure to the most current patchlevel. Usually this has to be done on all cluster nodes separately and requires some time and effort. But what about patching the software before setting up the cluster?

At the DOAG database conference in May, Andrew Mendelsohn announced that Oracle will change the release schedule to annual releases and that patch naming will be changed to “Release Updates” (RU). The latter started – as announced – in July 2017 and now the first “Database Release Update” is available.
Let’s start patching.
